The CONSTMACH T-120 mobile tertiary impact crushing plant is the highest-capacity model in the T series and is used as a finishing stage for manufactured sand and fine aggregate. The sections below cover the materials it processes, the products it makes, the industries it serves, how it compares with VSI plants, and how it integrates into a wider plant.
Which materials can be processed
The T-120 processes pre-crushed stone of varying hardness. CONSTMACH lists suitable feed materials as:
- Granite
- Basalt
- Dolomite
- Gabbro
- Limestone
Feed is normally material that has passed through primary and secondary crushing, with a maximum feeding size of 150 mm.
What products it makes
The plant produces manufactured sand and graded fine aggregate. With its three-deck vibrating screen it can deliver a 0-5 mm sand fraction together with up to three additional sized fractions simultaneously. The impact crushing action is used to obtain a cubical particle shape.
Which industries use it
The T-120 is applied where manufactured sand and shaped fine aggregate are needed, including:
- Ready-mixed concrete production
- Asphalt and road base supply
- Aggregate quarrying and processing
T series tertiary impact versus V series VSI: when to choose which
The T series uses a horizontal-shaft tertiary impact crusher, while the V series uses a vertical shaft impactor. The T-120 accepts a larger feed size (150 mm) than the comparable VSI units and reduces material by impact against breaker plates. A VSI plant accelerates material against anvils or a rock bed and is commonly preferred for highly abrasive feed. The choice depends on feed abrasiveness, required gradation, and the unit's place in the circuit.
Wear parts and maintenance
As an impact crusher, the T-120 has consumable wear parts in the crushing chamber. Typical considerations include:
- Blow bars on the rotor
- Breaker (impact) plates and chamber liners
- Feeder and screen media
- Conveyor belts
Wear rates depend on the hardness and abrasiveness of the processed material, and chamber wear parts are inspected as part of routine operation.
Comparison to alternative configurations
Compared with a stationary tertiary plant, the mobile T-120 reduces site preparation and allows relocation. Compared with a cone crusher in the same finishing role, the tertiary impact crusher generally produces a higher fines content and a cubical shape suited to sand production, while cone crushers are typically associated with harder, more abrasive duty.
Plant integration
The T-120 carries its feeder, crusher, screen and conveyors on a single chassis and can run as a self-contained sand making stage or downstream of separate primary and secondary plants. Oversize material is returned to the crusher by the feedback conveyor, and sized products are discharged by the stockpile conveyors.
